Abstract (en)
[origin: EP2977159A1] An extrusion forming apparatus 1 includes an extruding section 10, a chamber drum 20, and a forming section 30. The extruding section 10 kneads a material including a ceramic raw material and extrudes a kneaded material. The chamber drum 20 has a first space portion 23 having a first extruding direction extending portion 23c through which the kneaded material is allowed to flow in an extruding direction, and a second space portion 24 which has a second extruding direction extending portion 24c extending in the extruding direction and a direction changing portion 24d bending from the extruding direction to a downward direction, to allow the kneaded material to flow in the downward direction changed from the extruding direction. The second space portion 24 has a sectional area obtained by isotropically decreasing a sectional area of a cross section perpendicular to a flow-through direction of the kneaded material in the first space portion 23. The forming section 30 has a die 36 to extrude a ceramic formed body.
